Detailed description of the invention
Referring to figs. 1 through Fig. 4, the screening transmission equipment embodiment that the utility model is used for sand screening is described further.
A kind of screening transmission equipment for sand screening, comprise agitator and be arranged on the transmitting device of agitator outlet below for screening sand, described transmitting device comprises screen box 1 and for by the fine sand after screening and the separation unit 6 of magazins' layout, described screen box 1 is arranged on the exit of agitator, be provided with the wide-meshed screen 2 for separating of large small impurities in described screen box 1, screen box 1 is separated into upper strata screen box 11 and lower floor's screen box 12 by described wide-meshed screen 2; Described screen box 1 lower end is provided with the bracing frame 3 for installing screen box 1, is provided with and supports spring 4 between described screen box 1 and bracing frame 3; Described screen box 1 is provided with the sediment ejection trough 5 be connected with lower floor screen box 12 away from the side of the outlet of agitator; Described separation unit 6 is arranged on below sediment ejection trough 5.By being arranged on the transmitting device below agitator, just can realize the mould sand conveying after by stirring in agitator and screen lock out operation efficiently simultaneously, and can mould sand can be made to cool fast by the exhaust hole 82 on transmitting device, next step operates mould sand to facilitate people, substantially reduces the sieving time of whole mould sand.
Described separation unit 6 comprises separator box 61 and fine screen mesh 62, and separator box 61 is separated into upper branch mailbox 611 and lower branch mailbox 612 by described fine screen mesh 62, and described upper branch mailbox 611 is positioned at below sediment ejection trough 5; Described lower branch mailbox 612 stretches out away from the side of screen box 1 and forms the observation panel 7 of opening upwards.
Described lower branch mailbox 612 is provided with dividing plate 8, forms the ventilation cavity 9 that can pass into gases at high pressure between described dividing plate 8 and lower branch mailbox 612 bottom surface; Described dividing plate 8 is provided with some exhaust projections 81 with exhaust hole 82, and described exhaust hole 82 is connected with ventilation cavity 9.First the mould sand completed in agitator the condition of high temperature after stirring can enter into the upper strata screen box 11 of screen box 1, after allowing by wide-meshed screen 2 can be larger by the aperture in sand dregs be isolated in lower floor's screen box 12, then will from sediment ejection trough 5 runner separation unit 6 through wide-meshed screen 2 sand that slightly step is screened, the fine screen mesh 62 of its sand again in separation unit 6 carries out screening operation, finally drops on the dividing plate 8 on lower branch mailbox 612.
The mould sand dropped on dividing plate 8 will be arranged on dividing plate 8, by the exhaust hole 82 of gases at high pressure and blow afloat, send separation unit 6 gradually, mould sand is made to complete whole screening operation, blown afloat by gases at high pressure like this and can either more efficient mould sand be carried out beating spreading, make mould sand finer and smoother, better quality, but also can lower the temperature to mould sand fast, be convenient for people to carry out next step process operation to mould sand or reuse, substantially reduce the circulation process of mould sand.
Described exhaust projection 81 is polygon-prism, and described each sidewall of exhaust projection 81 is all provided with an exhaust hole 82.So just just can discharge gases at high pressure from exhaust projection 81 to individual direction, the mould sand dropped on dividing plate 8 is blown afloat, this makes it possible to make mould is husky can be movable more violent on dividing plate 8, this makes it possible to the movement facilitating mould sand, and colliding with each other between mould sand can be increased, make mould sand finer and smoother.
Some spacing pins 10 are also equipped with above described dividing plate 8.By the effect that the effect of spacing pin 10 can stop the mould sand blown afloat by the exhaust hole 82 on exhaust projection 81, mould sand can be placed kick up, but also while colliding with mould sand, husky for the mould condensing into block beating can be spread, make mould sand more fine and smooth.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
